Concrete Sealing

Concrete sealing specialists

Dustproofer

Dusty concrete can cause problems to expensive machinery and once airborne poses a risk to health for workers when breathed in. It also makes more work in the way of cleaning and general maintenance.

Dustproofing  is a cost effective way to harden your concrete floor, make it more robust and reduce the issue of dust. The floor needs to be in good condition. Concrete sealing using water based products will not give your floor resistance to chemicals & acid. Clear resin sealers will give chemical resistance and a longer lifespan.

Old Slabs- clean & seal.
After years of heavy usage your industrial floor will have picked up wear and tear, forklift tyre marks, discolouration and even surface breakdown. We can clean your floor using a diamond grinder to remove the top layer of concrete. To finish we apply a concrete sealer / concrete hardener that will help reduce dust levels. 

Dilapidations- removing line markings and sealing

We are able to diamond grind to remove any line markings and walkways, then seal the floor with Everbuild concrete sealer.

 

Types of concrete sealers

Clear epoxy sealers will give a durable and long lasting finish. They resist chemical and soil spills and offer a dry film thickness of 200 microns per coat and have a gloss finish. Epoxy sealers are not UV stable.

Silicone based sealers will soak into the concrete and prevent water ingress once applied. We use Stormdry, it makes the concrete slightly darker for a few weeks then returns to its normal colour.

Polyurethane sealers are 2 part resin based, giving high traffic resistance and are UV stable. They cure to a gloss finish and are suitable for both internal and external floors. 

Water based epoxy sealers are best suited to new concrete with high moisture content. A 2 part system giving a dry film thickness of 100 microns per coat.

Frequently asked questions:

Clear epoxy sealers are most durable and also protect the floor from oil and chemical spills soaking into the concrete.
Water based acrylic sealers are more cost effective and heal reduce dusting of bare concrete floors.

Yes old concrete can be sealed, we usually prepare the surface with a light diamond grind to clean the floor then apply 2 coats of an epoxy or water based sealer.

If you pour a small amount of water on the surface, it will either soak into the concrete within a minute, meaning it it porous and could benefit from sealing. Alternatively it may bead up and sit on the surface, this is a sign the concrete is already sealed.

It is recommended to wait 30 days if using an epoxy sealer as the excess moisture in the slab needs to dissipate.

If using a water based overbuild type sealer we use a backpack sprayer to apply then back roll to ensure no puddles are left on the surface.
If using an epoxy we apply with a solvent resistant roller and cut in edges with a brush.

Case study: concrete sealing

We carried out a diamond grind to this industrial floor in London & applied 2 coats of concrete sealer. The video shows the application of 2nd coat by sprayer and back roll. This industrial unit was a film set for an upcoming movie, ‘Cash Truck.’ The movie set had areas of the floor painted. These coatings had to be removed when handing back the industrial unit.
